用法和例句

Then based on the improved FP-tree a frequent closed itemsets mining algorithm is provided to improve the effectiveness of mining frequent close itemsets.

在经典的频繁闭合项集挖掘算法中,如Closet与Closet+,当条件模式数据库很庞大时,频繁项集的数目将会急剧增长,算法的效率会逐步恶化,并且算法挖掘结果的有效性也随着大量冗余模式的产生而下降。

To solve this problem,an algorithm for mining non-redundant association rules based on closed itemset is proposed.

Mining frequent closed itemsets in unidirectional FP-tree;

在单向FP-tree上挖掘频繁闭项集

The set of frequent closed itemsets determines exactly the complete set of all frequent itemsets and is usually much smaller than the latter.

频繁闭项集惟一确定频繁项集且规模小得多,但挖掘频繁闭项集仍是很费时的。

Therefore,mining frequent closed itemsets in data streams becomes a new important problem in recent years,where algorithm Moment was regarded as a typical method of them.
